DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 and 2, a combination suitcase of the present invention is essentially comprised of a suitcase 1 and a detachable backpack 2. Wherein, the suitcase 1 related to a suitcase provided with wheels, or any form of a weekender may be made in any configuration. On four corners of the surface of one side of two sides of a penal 11 of the suitcase 1 are respectively disposed with a loop 111. As illustrated in FIG. 3, each loop 111 containing a hole 113 is secured in a slot 112; or alternatively, the loop 111 is made integrated at each corner of the panel 11.

The detachable backpack 2 made in a wide and flat form is provided each of its four corners a mating buckle 22 connected to the backpack with an elastic band 21; each buckle 22 contains a buckling button 221; and one or multiple pockets 23, 24 is provided to the detachable backpack 2.

Now referring to FIGS. 3, 4, 5, and 6, the backpack 2 is firmly secured to the surface of the panel 11 of the suitcase as illustrated in FIG. 1 by locking each buckling button 221 of the buckle 22 to its corresponding loop hole 113 of the loop 111. The backpack 2 protects the panel 11 of the suitcase 1 from damage by scratch while increasing the storage space of the suitcase 1 to help maintain the appearance of the suitcase 1 as a whole and increase its service life.

As illustrated in FIG. 2, the backpack 2 may be detached from the panel 11 of the suitcase 1 to serve as a standalone carrier bag as desired;

or alternatively as illustrated in FIG. 7, a back strap 3 is attached to the buckle 22 for the backpack 2 to become a shoulder bag.

One pocket or multiple pockets 25 and two shoulder straps 26 are further provided to the back of the backpack 2. Both shoulder straps 26 are stored in the pocket 25 as illustrated in FIG. 8 when the backpack 2 is attached to the suitcase 1, and are pulled out when the backpack 2 is detached from the suitcase 1 to function as a sack as illustrated in FIG. 9.

According to FIG. 9, an insertion hole 27 is each disposed at four corners on the front or the back of the backpack 2 to receive and keep out of sight its respective buckle 22 when the backpack 2 is used as a standalone bag.

Each shoulder strap 26 allows adjustment of its length and another buckle 261 is disposed to the lower end of the shoulder strap 26 while another loop 271 is disposed at where corresponds to the buckle 261 for the buckle 261 to lock in the loop 271. The upper end of each shoulder strap 26 is fixed to the backpack 2 while the lower end of each shoulder strap 26 is locked to the backpack 2 by having the buckle 261 engaged in the loop 271.
